Description

Technical Field

[0001] The utility model belongs to the field of ground equipment traction, and particularly relates to a folding locking mechanism for converting the walking state of a bearing device. Background Technique

[0002] Traction trailers are widely used in the logistics fields of various industries and are a convenient means of transportation. In air transportation, in order to transport ground equipment onto an aircraft, traction trailers are usually used to move and carry the ground equipment.

[0003] In existing ground bearing equipment, flatbed trailers can achieve the movement and handling of equipment such as air conditioners. However, during actual use, the towing bar can only be fixed flat, occupying a large area when not in use. Moreover, when the locking mechanism with a fixed structure is used in cooperation with a tractor, due to the different specifications of different tractors, their towing heights are also different, which easily leads to poor flexibility when the tractor tows the flatbed trailer and is prone to rollover and jamming problems.

[0004] Therefore, in view of the problem of poor flexibility in the rotatable adjustment of the folding locking mechanism on the existing ground bearing device, a folding locking mechanism for converting the walking state of a bearing device is developed. By adding a hinge adjustment structure, a convex block limiting structure, a spring clamping structure, and a bolt connection structure to the locking mechanism, the existing locking mechanism can be stored on the upper surface of the ground trailer when not in use and can meet the towing needs and flexibility in different situations.
